Displaying Drawing Thumbnails in the Timeline View

T-ANIMPA-006-003

In the Timeline view, it is possible to preview the drawings in your scene by enabling the display of thumbnails for your drawing layers. You can display the thumbnail for all drawing layers or for individual drawing layers. This allows you to preview the drawing in the current frame as well as drawings exposed in every frame of your scene, which can be useful for managing your drawings and for adjusting their timing.

You can enable Thumbnails for all drawing layers simultaneously or for individual drawing layers. When thumbnails are displayed for a layer, the Timeline view also displays the name of each drawing as well as the amount of frames on which each drawing is exposed for that layer. Enabling thumbnails on a layer also gives access to that layer's Opacity parameter in the left panel of the Timeline view.

In the Timeline view, left of the layer's name, click on the Show/Hide Thumbnails button.

In the Timeline view, select the layer and press T.

Even when thumbnails are displayed for a layer, it is likely that you won't be able to see the full thumbnails for individual drawings that are exposed over 1 or 2 frames because, by default, frames are not large enough to display their thumbnails. To make the frames larger so that thumbnails have enough horizontal space to be displayed, you must zoom in on the Timeline view.

Set the focus on the Timeline view, for example by clicking on the Timeline view tab.

Do one of the following:

Drag the Timeline Zoom slider to the right.

Click on the Timeline view's tab, then press 2 repeatedly.

Move the mouse cursor in the Timeline view, then hold Ctrl (Windows/Linux) or ⌘ (macOS) and roll the mouse wheel up.

TIP: If you animate mostly on twos or threes, you can adjust the Timeline zoom to fully display the thumbnails of drawings exposed over two or three frames, or you can zoom in enough to display the thumbnails of drawings exposed over a single frame, depending on your preference.

TIP: To reset the Timeline Zoom to its default zoom level, click on the Reset Zoom icon left of the Timeline Zoom slider.

NOTE: When zoomed in on the Timeline view, you can tweak the exposure of your drawing by dragging the edges of the drawings with your mouse cursor. This is especially useful when displaying thumbnails as you can visually adjust the timing of your animation.
